I was set up next to PA at OLEY, and he said I should post pictures of the cast aluminum primary covers I now have in production.
They are made in 2 widths. The narrow one to fit the KR's and XR 750's, while the wider fits the competition Sportster models, wider clutch without the compensator engine sprocket.
Both can ordered with a racer type crankshaft starter kit.
All made by me in the USA. THEY FIT
Here is a link to the web page (I never have been able to post pictures).
